Can I change the input power plug on my 120Vac Smart-UPS?

Cause:
All Smart-UPS 2000VA or larger have an input plug that is not a standard 5-15 household style plug.

Resolution:
The higher capacity of these UPS models require an input plug that is either 20amp or 30 amp (depending on model) rather than the traditional 15 amp household plug you may be more familiar with. The UL listing of the UPS assumes that the UPS is using the input plug for which it was designed. Modifying the input plug may affect the UL or other regulatory compliance. Schneider Electric does not recommend modifying the input plug of your Smart-UPS UPS or attached Smart-UPS Accesories (IE: Stepdown Transformers, PDU strips, ETC)

Note: If you decide to go against this recommendation and change the input plug of your UPS, please be aware that the functional capacity of the UPS will be limited by the input circuit.
(I E: An SMT3000 being supplied 15 amps is effectively a 1500VA UPS rather than the 3000VA that it is rated for.)
